All works by Ravel are public domain since January 1st, 2008, in the EU and in all countries where the copyright term is 70 years from the death of the author.

The only exception is France as the so-called "Prorogations de guerre" apply to works published before the world wars. Boléro was premiered in 1928 so the second world war extension (8 years and 120 days) applies. Therefore Boléro will enter public domain in France on April 30, 2016.

The IMSLP-EU server is located in The Netherlands, so on the server side Boléro is certainly public domain. On the client side, especially French users should not neglect the disclaimer that is shown to them before downloading:
